Is taking finasteride effective for benign prostatic hyperplasia (BPH)?
Finasteride is commonly available in tablet and capsule formulations. Generally, finasteride can be effective for treating benign prostatic hyperplasia (BPH), but must be used under medical supervision. Detailed explanation is as follows:
Finasteride inhibits the conversion of testosterone to dihydrotestosterone (DHT), which is a key substance promoting the proliferation of prostate tissue cells. By reducing DHT production, finasteride can slow the progression of prostate enlargement. In some patients, prostate volume may decrease to a certain extent after treatment, thereby relieving pressure on the urethra and improving symptoms such as difficulty urinating, frequent urination, and weak urine flow, helping to maintain normal urinary function. However, it should be noted that finasteride cannot completely eliminate existing hyperplastic tissue, and long-term regular use is required to maintain its therapeutic effect.
During treatment, it is essential to strictly follow medical instructions; do not adjust the dosage or discontinue the medication without consulting a physician. Discontinuation may lead to a rebound increase in DHT levels and recurrence of symptoms. Regular follow-up evaluations of prostate volume and liver function are necessary to monitor therapeutic response and potential adverse effects. If abnormalities such as breast tenderness or changes in libido occur during treatment, medical attention should be sought promptly. Patients with impaired liver or kidney function should inform their physician of their condition before starting treatment, so that the physician can assess the suitability of the medication.
